Cloak could still trap Flash by keeping him stuck in between dimensions. He'd just have to create a succession of dimensional apertures which Flash would pass through, weakening each time. Don't forget that Cloak's Darkness Dimension saps the lifeforces of the beings that inhabit/pass through it without Dagger's light to protect them. Flash has an enhanced metabolic rate, but he only has one normal soul.
It's not as simple as it seems...

Possible scenario. Although with his multitudes of dimensional travel (he's been stuck before) he could get out.Or he could unleash the Speed Force energy....which I have no idea what would happen to the Cloak. Doing that has opened/destroyed/???? dimensional portals.
Speed Force Energy? He'd speed up/slow down the rate of the aperture's growth?
How would that destroy it?
It may help Flash avoid it if he slowed down the rate of expansion, but other than that, he can't really do anything to Cloak, and that tactic is not even an offensive move, it's evasion/defensive. If he attacks Cloak physically he'd be absorbed into darkness, and solid objects (projectiles) pass through Cloak (he's like a living shadow).
